Abstract (en)
[origin: WO2010136685A2] The invention relates to a device for controlling the orientation of the blades of a turboprop fan, comprising at least one set (24a) of fan blades (26) of adjustable orientation coupled in rotation to a rotary ring (28a) coaxial with a longitudinal axis (12) and connected mechanically to a turbine rotor, each blade of the set being coupled, for adjustment of its orientation, to a synchronizer ring (30a) coaxial with the longitudinal axis. The device also includes an actuator (38) coupled in rotation to the turbine rotor and connected mechanically to the synchronizer ring by means of a plurality of connecting arms (40a) connected to the actuator rod (44) and hinged to the synchronizer ring in such a way that an actuation of the actuator causes a rotational movement of the synchronizer ring about the longitudinal axis.
